Peterhouse is a community of three schools:

1. Peterhouse Boys (PHB) – a full boarding school for boys from Form 1 to 6th form (with girls from Peterhouse Girls being taught at 5th and 6th form level)
2. Peterhouse Girls (PHG) – a full boarding school, with a small number of day pupils, for girls from Form 1 to 6th form
3. Springvale House – a weekly boarding and day school for boys and girls from Grade 1 to Grade 7
4. In addition there is a Nursery School for boys and girls located at PHB

PHB, PHG and SVH operate as a group of schools. The Rector is Headmaster on a day-to-day basis of PHB and he also has overall responsibility for the leadership of the Peterhouse Group. PHG and SVH are led by their own Headmasters who report to the Rector whilst having considerable autonomy of their own. The Business Manager, working in close liaison in particular with the Rector, but also with the Headmasters of PHG and SVH has responsibility for the management of the three schools support staff and their various activities (catering, estates, finance, maintenance and transport).
